Definitions
- the present invention relates to mixtures of emulsions with dispersions of polymer. It relates more particularly to the stability of a dispersion of polyol together with an isocyanate emulsion, most often masked.
- compositions are particularly useful for varnishes and painting, but they can be useful for any application using the properties of isocyanate condensation. They can also be useful in any field in which we have to coexist isocyanate emulsions, in general blocked, with dispersions of insoluble alcohols of grain size different and especially in the formulations for agriculture.
- dispersion will be used for polymers with hydroxyl functions and in particular polyols, however that will use the expression emulsions for isocyanates, blocked or not.
- the mixture of dispersions may also contain pigments and charges is then deposited on a support in the form of a film using classic techniques for using industrial paints.
- the preparation contains blocked isocyanates
- the whole film plus support is cooked at a temperature sufficient to ensure the unlocking of functions isocyanates and the condensation of these with hydroxyl groups polyol particles.
- the particle size characteristics often refer to notations of the type d n where n is a number from 1 to 99, this notation is well known in many technical fields, but is a little more rare in chemistry, also may it be useful to recall its meaning.
- This notation represents the particle size such that n% (by weight, or more exactly by mass, since the weight is not an amount of matter but a force) of the particles is less than or equal to said size.
- the ratios of the average sizes (d 50 ) between the isocyanate emulsion and the polyol dispersion are between 2 and 200.
- the average sizes of the isocyanate emulsions manufactured according to the technique described in the French patent application filed on 03.31.1993 under No. 93 03795 and published under No. 2703358 on 07.10.94 have average sizes between 0.1 and 10 micrometers and more generally between 0.3 and 2 micrometers.
- the polyol dispersions used in combination with these emulsions have average sizes measured by quasi-elastic light scattering of between 20 and 200 nanometers and more generally between 50 and 150 nanometers.
- this instability results in a macroscopic separation fast, generally in a few minutes, to give a phase on the one hand fluid and on the other hand a very viscous phase.
- one of the aims of the present invention is to provide a technique which provides stable and fluid mixtures of an isocyanate emulsion with polyol dispersions which are stable "per se", in particular without it should be added additional additive or neutralizer for example for adjust a pH.
- Another object of the present invention is to provide compositions comprising an emulsion of masked isocyanates and a dispersion of polyols which are physically stable for at least one month.
- the other object of the invention is to obtain, from these stable and fluid mixtures of this emulsion with a polyol dispersion, films having good gloss, transparency and resistance to solvents.
- the polydispersity index defined as (d 90 -d 10 ) / d 50 is at most equal to 2 advantageously equal to 1. The best results being obtained for values of 0.9 to 0, 8 or less.
- R when R is between 2 and 10, it is the constraint that the polyol content expressed in percent by mass is at least equal to 35-0.75R, advantageously at least equal to 40-0.75R, preferably at 45-0.75R, which gives the most significant area of existence.
- R between 10 and 15 it is possible to find viable solutions in one or the other field defined by the inequalities above.
- solutions to the problems posed can hardly be found except in the field defined by the condition that the polyol content expressed in percent by mass is at most equal to 45-2R, advantageously at most equal to 40- 2R, preferably 35-2R.
- the ratio between the number of hydroxyl functions and the number of isocyanate functions, masked or not, can vary very widely as has been indicated above.
- the ratios lower than the stoichiometry are favorable to plasticity, while that ratios higher than the stoichiometry lead to coatings of high hardness. It is rare that we have reports deviating from the range from 0.5 to 2. However, in most cases and for the most common uses, in order to obtain satisfactory varnish or paint films, it is preferable that the quantity, expressed in equivalent, of reactive blocked isocyanates is substantially equal to that of free and reactive alcohol functions, expressed in equivalent, that is to say respond to stoichiometry. As an indication, one can indicate that there is a tolerance of more or less 20% compared to the stoichiometry, but it is preferable to use only a tolerance of more or less 10 or 20%.
- Isocyanate emulsions are advantageously made according to the technique described in the French patent application published under No. 2703358 on 07.10.94, filed on 31.03.1993 under No. 93 03795 and entitled: "Process for the preparation of aqueous emulsions advantageously masked oils and / or gums and / or (poly) isocyanate resins and emulsions obtained ".
- composition according to the present invention further comprises at least one catalyst for the release of masked isocyanates, and in particular of catalysts, latent or not, based on tin.
- catalysts can be found either within the polyol phase or within the phase masked isocyanate, either in dispersed form within the aqueous phase keep on going. They can finally be dissolved in the aqueous phase.
- the polyol dispersions which can be used for the invention are the conventional products used in the paint and varnish industry. They are most often (co) polymers) produced in emulsion according to the conventional methods of radical or bulk polymerization.
- any known pigment may be added, to provided that it is inert with respect to the constituents of the composition.
- the isocyanates preferred are those which are masked in particular by the masking agents in themselves known such as phenols, ketone oximes and in particular that of methyl ethyl ketone, the various pyrazoles.
- the preferred isocyanates are those in which the nitrogen of at least one of the isocyanate functions is attached to a sp 3 hybridization carbon advantageously carrying one, and preferably two, hydrogen atom (s). Isocyanates, all of whose functions have this characteristic (with possibly its preferred options), are highly appreciated.
- isocyanates masked or not, which have a or several isocyanuric rings and / or at least one of the functionalities of biuret or dimer type.
- isocyanates having both characteristics specified above, i.e. oligomerism and aliphatic character on at least one of the isocyanate functions.
- the water content of said compositions is at least equal to a third of the mass of the composition advantageously at least 2/5.
- the preferred polyols are in the form of an aqueous dispersion, they have a average size less than 200 nanometers which presents a greater formulation latitude in combination with isocyanate emulsions.
- aqueous dispersions with a low content of compounds soluble in water such as alcohols and amines which can lead to the coalescence of the isocyanate emulsion. It is therefore very desirable that the cumulative content of various alcohols and amines is less than those which induce a coalescence of the isocyanate emulsion.
- the present invention also relates to the coatings obtained from the compositions according to the present invention.
- These coatings can be obtained by crosslinking, in particular by baking at a temperature close to that corresponding to the release of the masked isocyanates optionally in the presence of one or more catalysts.

Abstract
Description
La présente invention concerne des mélanges d'émulsions avec des dispersions de polymère. Elle concerne plus particulièrement la stabilité d'une dispersion de polyol conjointement avec une émulsion d'isocyanate, le plus souvent masqué.The present invention relates to mixtures of emulsions with dispersions of polymer. It relates more particularly to the stability of a dispersion of polyol together with an isocyanate emulsion, most often masked.
De telles compositions sont notamment utiles pour les vernis et la peinture, mais elles peuvent être utiles pour toute application utilisant les propriétés de condensation des isocyanates. Elles peuvent également être utiles dans tout domaine dans lequel on a à faire coexister des émulsions d'isocyanates, en général bloqués, avec des dispersions d'alcools insolubles de granulométrie différente et notamment dans les formulations pour l'agriculture.Such compositions are particularly useful for varnishes and painting, but they can be useful for any application using the properties of isocyanate condensation. They can also be useful in any field in which we have to coexist isocyanate emulsions, in general blocked, with dispersions of insoluble alcohols of grain size different and especially in the formulations for agriculture.
Dans la suite de la présente description, on utilisera le terme de dispersion pour les polymères à fonctions hydroxyles et notamment les polyols cependant qu'on utilisera l'expression émulsions pour les isocyanates, bloqués ou non.In the remainder of this description, the term dispersion will be used for polymers with hydroxyl functions and in particular polyols, however that will use the expression emulsions for isocyanates, blocked or not.
L'utilisation de solvants organiques est de plus en plus souvent critiquée par les autorités en charge de la sécurité du travail, car ces solvants, ou du moins certains d'entre eux, sont réputés toxiques ou chronotoxiques. C'est la raison pour laquelle on essaye de développer de plus en plus des techniques qui se substituent aux techniques en milieu solvant pour pallier les inconvénients afférents aux solvants.The use of organic solvents is increasingly criticized by authorities responsible for work safety, because these solvents, or at least some of them are considered toxic or chronotoxic. That's the reason for which we are trying to develop more and more techniques which replace techniques in a solvent medium to overcome the drawbacks related to solvents.
Une des solutions les plus souvent utilisées réside dans l'utilisation d'émulsions ou de dispersions dans l'eau.One of the most often used solutions is the use of emulsions or dispersions in water.
Pour réaliser des films de peintures ou de vernis, on mélange deux dispersions, une émulsion contenant l'isocyanate qui peut être bloqué et une dispersion de polyol.To make films of paints or varnishes, two dispersions are mixed, an emulsion containing the isocyanate which can be blocked and a dispersion of polyol.
Le mélange des dispersions pouvant également contenir des pigments et des charges est alors déposé sur un support sous forme d'un film à l'aide des techniques classiques de mise en oeuvre des peintures industrielles. Lorsque la préparation contient des isocyanates bloqués, l'ensemble film plus support est cuit à une température suffisante pour assurer le déblocage des fonctions isocyanates et la condensation de celles-ci avec des groupements hydroxyles des particules de polyol.The mixture of dispersions may also contain pigments and charges is then deposited on a support in the form of a film using classic techniques for using industrial paints. When the preparation contains blocked isocyanates, the whole film plus support is cooked at a temperature sufficient to ensure the unlocking of functions isocyanates and the condensation of these with hydroxyl groups polyol particles.
Dans la présente description, les caractéristiques de granulométrie font souvent
référence à des notations du type dn où n est un nombre de 1 à 99, cette notation
est bien connue dans de nombreux domaines techniques, mais est un peu plus
rare en chimie, aussi peut-il être utile d'en rappeler la signification. Cette notation
représente la taille de particule telle que n % (en poids, ou plus exactement en
masse, puisque le poids n'est pas une quantité de matière mais une force) des
particules soit inférieur ou égal à ladite taille.
Dans la suite de la description, on utilisera l'indice de polydispersité, lequel est
défini comme
In the following description, the polydispersity index will be used, which is defined as
Typiquement, les rapports des tailles moyennes (d50) entre l'émulsion d'isocyanate et la dispersion de polyol sont compris entre 2 et 200. Ainsi les tailles moyennes des émulsions d'isocyanates fabriquées selon la technique décrite dans la demande de brevet français déposée le 31.03.1993 sous le n° 93 03795 et publiée sous le n° 2703358 le 07.10.94, ont des tailles moyennes comprises entre 0,1 et 10 micromètres et plus généralement entre 0,3 et 2 micromètres. Les dispersions de polyols utilisées en association avec ces émulsions ont des tailles moyennes mesurées par diffusion quasi élastique de la lumière comprises entre 20 et 200 nanomètres et plus généralement comprises entre 50 et 150 nanomètres.Typically, the ratios of the average sizes (d 50 ) between the isocyanate emulsion and the polyol dispersion are between 2 and 200. Thus the average sizes of the isocyanate emulsions manufactured according to the technique described in the French patent application filed on 03.31.1993 under No. 93 03795 and published under No. 2703358 on 07.10.94, have average sizes between 0.1 and 10 micrometers and more generally between 0.3 and 2 micrometers. The polyol dispersions used in combination with these emulsions have average sizes measured by quasi-elastic light scattering of between 20 and 200 nanometers and more generally between 50 and 150 nanometers.
Lorsque l'on mélange des dispersions de tailles différentes, ce qui est généralement le cas, de manière à obtenir des rapports molaires entre les groupements NCO et OH compris entre 0,3 à 10 et plus préférentiellement entre 0,8 et 1,5, on observe une instabilité des mélanges des deux dispersions.When mixing dispersions of different sizes, which is generally the case, so as to obtain molar ratios between the NCO and OH groups between 0.3 to 10 and more preferably between 0.8 and 1.5, instability of the mixtures of the two dispersions is observed.
A titre d'exemple, cette instabilité se traduit par une séparation macroscopique rapide, en quelques minutes généralement, pour donner d'une part une phase fluide et d'autre part une phase très visqueuse.For example, this instability results in a macroscopic separation fast, generally in a few minutes, to give a phase on the one hand fluid and on the other hand a very viscous phase.
Il s'ensuit non seulement une impossibilité à conserver (stocker) ces mélanges,
mais aussi une difficulté extrême à appliquer ce mélange sur la surface que l'on
désire recouvrir selon les techniques usuelles d'application des peintures et des
vernis. Si on fait en sorte d'appliquer ces mélanges instables sur un support, tel
que sur une plaque de verre ou métallique, le film résultant n'est pas transparent
mais apparaít opaque et hétérogène et donc ne convient pas.
Pour résoudre ce problème, la demande européenne publiée sous le
n° 0 358 979 propose d'utiliser un polyol dans lequel on émulsifie
l'isocyanate ; la demande postérieure du même déposant n° 0 557 844
propose une solution similaire en utilisant, le cas échéant, des
épaississants.
Ces problèmes sont particulièrement aigus dans le cas d'isocyanates, masqués
ou non, lorsqu'ils sont mélangés à des polyols non solubles, dispersés dans l'eau.It follows not only an impossibility of preserving (storing) these mixtures, but also an extreme difficulty in applying this mixture on the surface which it is desired to cover according to the usual techniques for applying paints and varnishes. If we make sure to apply these unstable mixtures on a support, such as on a glass or metal plate, the resulting film is not transparent but appears opaque and heterogeneous and therefore not suitable.
To solve this problem, the European application published under No. 0 358 979 proposes using a polyol in which the isocyanate is emulsified; the same applicant's subsequent application No. 0 557 844 proposes a similar solution using, where appropriate, thickeners.
These problems are particularly acute in the case of isocyanates, masked or not, when they are mixed with non-soluble polyols dispersed in water.
Ainsi, un des buts de la présente invention est de foumir une technique qui permette de fournir des mélanges fluides et stables d'une émulsion isocyanates avec des dispersions de polyols qui soient stables "per se", notamment sans qu'il y ait lieu d'ajouter d'additif supplémentaire ou de neutralisant par exemple pour ajuster un pH.Thus, one of the aims of the present invention is to provide a technique which provides stable and fluid mixtures of an isocyanate emulsion with polyol dispersions which are stable "per se", in particular without it should be added additional additive or neutralizer for example for adjust a pH.
Un autre but de la présente invention est de fournir des compositions comportant une émulsion d'isocyanates masqués et une dispersion de polyols qui soient physiquement stables pendant un mois au moins.Another object of the present invention is to provide compositions comprising an emulsion of masked isocyanates and a dispersion of polyols which are physically stable for at least one month.
L'autre but de l'invention est d'obtenir, à partir de ces mélanges stables et fluides de cette émulsion avec une dispersion de polyol, des films présentant de bonnes propriétés de brillance, transparence et résistance aux solvants.The other object of the invention is to obtain, from these stable and fluid mixtures of this emulsion with a polyol dispersion, films having good gloss, transparency and resistance to solvents.
Ces buts sont atteints au moyen d'une composition comportant :
- - au moins un polyisocyanate masqué ou non sous la forme d'une émulsion aqueuse dont la taille moyenne est comprise entre 0,1 et 10 micromètres et de préférence inférieure à 2 et supérieure à 0,2 micromètre.
- - au moins un polymère polyhydroxylé, avantageusement un polyol, sous
forme d'une dispersion aqueuse dont la taille moyenne est comprise entre 10
et 200 nanomètres. La quantité en polymère(s) polyhydroxylé(s) du
mélange étant choisie de manière à répondre à l'une des deux
contraintes suivantes :
- la teneur en polymère(s) polyhydroxylé(s) exprimée en pour cent massique est au moins égale à 35 - 0,75 R, avantageusement au moins égale à 40 - 0,75 R, de préférence à 45 - 0,75 R ;
- la teneur en polymère(s) polyhydroxylé(s) exprimée en pour cent massique est au plus égale à 45 - 2 R, avantageusement au plus égale à 40 - 2 R, de préférence à 35 - 2 R ;
Il est très souhaitable que l'émulsion et /ou la dispersion soit aussi peu dispersée que possible.
Ainsi pour les polymères polyhydroxylés, l'indice de polydispersité (défini comme I = (d90-d10)/d50) est au plus égal à 2 avantageusement égal à 1, les meilleurs résultats étant obtenus pour des valeurs de 0,2 à 0,1 voire moins. These aims are achieved by means of a composition comprising:
- - At least one polyisocyanate masked or not in the form of an aqueous emulsion whose average size is between 0.1 and 10 micrometers and preferably less than 2 and more than 0.2 micrometer.
- - At least one polyhydroxylated polymer, advantageously a polyol, in the form of an aqueous dispersion whose average size is between 10 and 200 nanometers. The quantity of polyhydroxylated polymer (s) of the mixture being chosen so as to meet one of the following two constraints:
- the content of polyhydroxylated polymer (s) expressed in mass percent is at least equal to 35 - 0.75 R, advantageously at least equal to 40 - 0.75 R, preferably 45 - 0.75 R;
- the content of polyhydroxylated polymer (s) expressed in percent by mass is at most equal to 45 - 2 R, advantageously at most equal to 40 - 2 R, preferably 35 - 2 R;
It is very desirable that the emulsion and / or dispersion be as little dispersed as possible.
Thus for polyhydroxylated polymers, the polydispersity index (defined as I = (d 90 -d 10 ) / d 50 ) is at most equal to 2 advantageously equal to 1, the best results being obtained for values of 0.2 0.1 or less.
Ainsi pour les polyisocyanates masqués ou non l'indice de polydispersité défini comme (d90-d10)/d50 est au plus égal à 2 avantageusement égal à 1. Les meilleurs résultats étant obtenus pour des valeurs de 0,9 à 0,8 voire moins.Thus for the polyisocyanates masked or not the polydispersity index defined as (d 90 -d 10 ) / d 50 is at most equal to 2 advantageously equal to 1. The best results being obtained for values of 0.9 to 0, 8 or less.
Les zones de formulation dépendent du rapport R des tailles moyennes (d50)
entre l'émulsion d'isocyanate et celles de la dispersion de polymère(s)
polyhydroxylé(s), avantageusement de polyols.
R est égal à la taille moyenne de l'émulsion sur la taille moyenne de la
dispersion de polymère polyhydroxylé, avantageusement de polyol.
Selon l'invention, la quantité en polymère polyhydroxylé, avantageusement en
polyol, du mélange est choisie de manière à répondre à l'une des deux
contraintes suivantes :
- la teneur en polymère polyhydroxylé, avantageusement en polyol, exprimée en pourcent massique est au moins égale à 35 - 0,75R, avantageusement au moins égale à 40 - 0,75R, de préférence à 45 - 0,75R ;
- la teneur en polymère polyhydroxylé, avantageusement en polyol, exprimée en pourcent massique est au plus égale à 45-2R, avantageusement au plus égale à 40-2R, de préférence à 35- 2R
En d'autre terme R = (d50 de l'émulsion)/(d50 de la dispersion).The formulation zones depend on the ratio R of the average sizes (d 50 ) between the isocyanate emulsion and those of the dispersion of polyhydroxylated polymer (s), advantageously of polyols.
R is equal to the average size of the emulsion over the average size of the dispersion of polyhydroxylated polymer, advantageously of polyol.
According to the invention, the quantity of polyhydroxylated polymer, advantageously polyol, of the mixture is chosen so as to meet one of the following two constraints:
- the content of polyhydroxylated polymer, advantageously of polyol, expressed in percent by mass is at least equal to 35 - 0.75R, advantageously at least equal to 40 - 0.75R, preferably to 45 - 0.75R;
- the content of polyhydroxylated polymer, advantageously of polyol, expressed in percent by mass is at most equal to 45-2R, advantageously at most equal to 40-2R, preferably at 35-2R
In other words R = (d 50 of the emulsion) / (d 50 of the dispersion).
Ainsi, lorsque R est compris entre 2 et 10, c'est la contrainte selon laquelle la
teneur en polyol exprimée en pourcent massique est au moins égale à 35-0,75R,
avantageusement au moins égale à 40-0,75R, de préférence à 45-0,75R, qui
donne la zône d'existence la plus significative.
Pour R compris entre 10 et 15, il est possible de trouver des solutions viables
dans l'un ou l'autre domaine défini par les inégalités ci-dessus.
Pour R supérieur à 15, on ne peut guère trouver de solutions aux problèmes
posés que dans le domaine défini par la condition selon laquelle la teneur en
polyol exprimée en pourcent massique est au plus égale à 45-2R,
avantageusement au plus égale à 40-2R, de préférence à 35- 2R.
Ainsi dans le domaine où R est compris entre 10 et 15, deux zones d'existence
stables coexistent .
Le rapport entre le nombre de fonctions hydroxyles et le nombre de fonctions
isocyanates, masquées ou non, peut varier très largement comme cela a été
indiqué ci-dessus. Thus, when R is between 2 and 10, it is the constraint that the polyol content expressed in percent by mass is at least equal to 35-0.75R, advantageously at least equal to 40-0.75R, preferably at 45-0.75R, which gives the most significant area of existence.
For R between 10 and 15, it is possible to find viable solutions in one or the other field defined by the inequalities above.
For R greater than 15, solutions to the problems posed can hardly be found except in the field defined by the condition that the polyol content expressed in percent by mass is at most equal to 45-2R, advantageously at most equal to 40- 2R, preferably 35-2R.
Thus in the domain where R is between 10 and 15, two stable zones of existence coexist.
The ratio between the number of hydroxyl functions and the number of isocyanate functions, masked or not, can vary very widely as has been indicated above.
Les rapports inférieurs à la stoechiométrie sont favorables à la plasticité,
cependant que des rapports supérieurs à la stoechiométrie conduisent à des
revêtements de forte dureté. Il est rare que l'on ait des rapports s'écartant du
domaine allant de 0,5 à 2.
Toutefois, dans la plupart des cas et pour les utilisations les plus courantes, pour
obtenir des films de vernis ou de peinture qui soient satisfaisants, il est
préférable que la quantité, exprimée en équivalent, d'isocyanates bloqués
réactifs soit sensiblement égale à celle des fonctions alcool libres et réactives,
exprimée en équivalent, c'est-à-dire répondent à la stoechiométrie. A titre
indicatif, on peut indiquer qu'il existe une tolérance de plus ou moins 20% par
rapport à la stoechiométrie, mais il est préférable de n'utiliser qu'une tolérance de
plus ou moins 10 ou 20%.
Les émulsions de isocyanates sont avantageusement faites selon la technique
décrite dans la demande de brevet français publiée sous le n°2703358 le
07.10.94, déposée le 31.03.1993 sous le n° 93 03795 et intitulée : "Procédé de
préparation d'émulsions aqueuses d'huiles et/ou de gommes et/ou de résines
(poly)isocyanates avantageusement masqués et émulsions obtenues".The ratios lower than the stoichiometry are favorable to plasticity, while that ratios higher than the stoichiometry lead to coatings of high hardness. It is rare that we have reports deviating from the range from 0.5 to 2.
However, in most cases and for the most common uses, in order to obtain satisfactory varnish or paint films, it is preferable that the quantity, expressed in equivalent, of reactive blocked isocyanates is substantially equal to that of free and reactive alcohol functions, expressed in equivalent, that is to say respond to stoichiometry. As an indication, one can indicate that there is a tolerance of more or less 20% compared to the stoichiometry, but it is preferable to use only a tolerance of more or less 10 or 20%.
Isocyanate emulsions are advantageously made according to the technique described in the French patent application published under No. 2703358 on 07.10.94, filed on 31.03.1993 under No. 93 03795 and entitled: "Process for the preparation of aqueous emulsions advantageously masked oils and / or gums and / or (poly) isocyanate resins and emulsions obtained ".
En ce qui concerne les éléments additionnels d'une composition selon la présente invention, il est possible qu'elle comporte en outre au moins un catalyseur de libération des isocyanates masqués, et notamment des catalyseurs, latents ou non, à base d'étain. On peut signaler que ces catalyseurs peuvent se trouver, soit au sein de la phase polyol, soit au sein de la phase isocyanate masqué, soit sous forme dispersée au sein de la phase aqueuse continue. Ils peuvent enfin être dissous dans la phase aqueuse .With regard to the additional elements of a composition according to the present invention, it is possible that it further comprises at least one catalyst for the release of masked isocyanates, and in particular of catalysts, latent or not, based on tin. It can be noted that these catalysts can be found either within the polyol phase or within the phase masked isocyanate, either in dispersed form within the aqueous phase keep on going. They can finally be dissolved in the aqueous phase.
Les dispersions de polyols utilisables pour l'invention sont les produits classiques utilisés dans l'industrie des peintures et vernis. Ce sont le plus souvent des (co)polymères) fabriqués en émulsion selon les procédés classiques de la polymérisation radicalaire ou en masse.The polyol dispersions which can be used for the invention are the conventional products used in the paint and varnish industry. They are most often (co) polymers) produced in emulsion according to the conventional methods of radical or bulk polymerization.

Ces produits se présentent sous forme de dispersions aqueuses (ou émulsions) avec des extraits secs compris entre 20 et 60%. Les polyols sont caractérisés par leur taux de groupements hydroxyles qui sont, soient donnés par le fabricant soient dosés analytiquement.These products are in the form of aqueous dispersions (or emulsions) with dry extracts between 20 and 60%. Polyols are characterized by their rate of hydroxyl groups which are given by the manufacturer are assayed analytically.
Dans le cas des peintures, il peut être ajouté tout pigment connu en lui-même, à condition qu'il soit inerte vis-à-vis des constituants de la composition.In the case of paints, any known pigment may be added, to provided that it is inert with respect to the constituents of the composition.
Quoiqu'il soit possible selon la présente invention d'utiliser les isocyanates non masqués, et comme ces derniers sont peu stables dans l'eau, les isocyanates préférés sont ceux qui sont masqués notamment par les agents de masquage en eux-mêmes connus tels que les phénols, les oximes de cétones et notamment celui de la méthyléthylcétone, les divers pyrazoles.Although it is possible according to the present invention to use non-isocyanates masked, and as these are not very stable in water, the isocyanates preferred are those which are masked in particular by the masking agents in themselves known such as phenols, ketone oximes and in particular that of methyl ethyl ketone, the various pyrazoles.
Les isocyanates préférés sont ceux dont l'azote d'au moins une des fonctions isocyanates est rattaché à un carbone d'hybridation sp3 portant avantageusement un, et de préférence deux, atome(s) d'hydrogène. Les isocyanates dont toutes les fonctions présentent cette caractéristique (avec éventuellement ses options préférées) sont très appréciés.The preferred isocyanates are those in which the nitrogen of at least one of the isocyanate functions is attached to a sp 3 hybridization carbon advantageously carrying one, and preferably two, hydrogen atom (s). Isocyanates, all of whose functions have this characteristic (with possibly its preferred options), are highly appreciated.
On peut en particulier citer les isocyanates, masqués ou non, qui présentent un ou plusieurs cycles isocyanuriques et/ou au moins une des fonctionnalités de type biuret ou dimère.Mention may in particular be made of isocyanates, masked or not, which have a or several isocyanuric rings and / or at least one of the functionalities of biuret or dimer type.
Il est préférable que les isocyanates présentant les deux caractéristiques spécifiées ci-dessus, à savoir oligomérie et caractère aliphatique sur au moins une des fonctions isocyanates.It is preferable that isocyanates having both characteristics specified above, i.e. oligomerism and aliphatic character on at least one of the isocyanate functions.
Avantageusement la teneur en eau desdites compositions est au moins égale à un tiers de la masse de la composition avantageusement au moins 2/5.Advantageously, the water content of said compositions is at least equal to a third of the mass of the composition advantageously at least 2/5.
Les polyols préférés se présentent sous forme de dispersion aqueuse, ils ont une taille moyenne inférieure à 200 nanomètres ce qui présente une plus grande latitude de formulation en association avec les émulsions d'isocyanates. On préfère des dispersions aqueuses à faible teneur en composés solubles dans l'eau tels que les alcools et les amines qui peuvent conduire à la coalescence de l'émulsion d'isocyanates. Il est donc très souhaitable que la teneur cumulée en divers alcools et amines soit inférieure à celles qui induisent une coalescence de l'émulsion d'isocyanates.The preferred polyols are in the form of an aqueous dispersion, they have a average size less than 200 nanometers which presents a greater formulation latitude in combination with isocyanate emulsions. We prefers aqueous dispersions with a low content of compounds soluble in water such as alcohols and amines which can lead to the coalescence of the isocyanate emulsion. It is therefore very desirable that the cumulative content of various alcohols and amines is less than those which induce a coalescence of the isocyanate emulsion.
La présente invention vise également les revêtements obtenus à partir des
compositions suivant la présente invention. Ces revêtements peuvent être
obtenus par réticulation, en particulier par cuisson à une température voisine de
celle correspondant à la libération des isocyanates masqués éventuellement en
présence d'un ou plusieurs catalyseurs.
Les exemples non limitatifs suivants illustrent l'invention.The present invention also relates to the coatings obtained from the compositions according to the present invention. These coatings can be obtained by crosslinking, in particular by baking at a temperature close to that corresponding to the release of the masked isocyanates optionally in the presence of one or more catalysts.
